Examples

• Single subscription:

public class Foo : IDisposable
{
    private IDisposable _sub;

    public Foo(IEventBus eventBus)
    {
        _sub = eventBus.Subscribe<EventA>(e => Debug.Log(e));
    }

    public void Dispose()
    {
        _sub.Dispose();
    }
}

• Bus subscription using IEventBusSubscriber interface:

public class Foo : IEventBusSubscriber, IDisposable
{
    private readonly IEventBus _eventBus;

    public Foo(IEventBus eventBus)
    {
        _eventBus = eventBus;
        _eventBus.Subscribe(this);
    }

    public void HandleEvent<T>(T e)
    {
        switch (e)
        {
            case EventA a:
                //...
            break;
        }
    }

    public void Dispose()
    {
        _eventBus.Unsubscribe(this);
    }
}
